Figui-e4 is a-ront elevation of a press and vshim therein similar tothat shown in. Figure3 illustrating a modification in which the edges of the shim material at the bolt hole therein are bent downwardly bya projection on the head of the press. 1

In the embodiment illustrated, the shim comprises a body portion'l, consisting of a plurality of laminae 2 of thin brass strips or the like, shaped accordingto the bearing which the .shim is to lit and provided-with one or more holes 3 therethru 'for the bolts Ywhich hold the parts of the bearing together.
